Re: ANNOUNCE: GHC 7.10.1 Release Candidate 1

I’ve had some issues building this (and the git HEAD), it seems that the config.guess and config.sub in the libffi tarball is old, it doesn’t detect the platform when building with msys2. I had to unpack the tarfile and update the files, after this it correctly built.

Then I proceeded to try to make a shared library and got the following warning:

ManualCheck.hs:18:1: Warning:
    the 'stdcall' calling convention is unsupported on this platform,
    treating as ccall
    When checking declaration:
      foreign export stdcall "testFoo" testFooA :: CInt -> IO (FooPtr)

Does this mean that GHC no longer supports stdcall on windows? or could this be related to issue I had building?

We are pleased to announce the first release candidate for GHC 7.10.1:

This includes the source tarball and bindists for 64bit/32bit Linux
and Windows. Binary builds for other platforms will be available
shortly. (CentOS 6.5 binaries are not available at this time like they
were for 7.8.x). These binaries and tarballs have an accompanying
SHA256SUMS file signed by my GPG key id (0x3B58D86F).

We plan to make the 7.10.1 release sometime in February of 2015. We
expect another RC to occur during January of 2015.

Please test as much as possible; bugs are much cheaper if we find them
before the release!
